ABSTRACT:
A liquid crystal display device capable of improving quality of moving images is provided. Each LED (Light Emitting Diode) block is turned ON according to a response of a liquid crystal corresponding to a light emitting region and the brightest gray level is detected for each of red (R), green (G) and blue (B) of an input video signal in every frame period and an input video signal is converted into a value obtained by being multiplied by an upper limit gray level and then by being divided by the brightest gray level and a gray level voltage corresponding to the converted value is applied to each data electrode and, during a lighting period of LED blocks, each LED block is made to flash at a duty corresponding to a rate of the brightest gray level to the upper limit gray level.
